Worried about the cold temperature. 17 under lights in storage container,12/12 cycle for 10 days now. Pretty sure are all female. Guessing another good 4 weeks until ready , but down to 39 degrees and getting colder. Am thinking of adding a couple 100w incandescent lights during the on time to generate some warmth. I have some Styrofoam panels around them but i don't think that is much help because the air temp is the concern? This is my first post, so I'm sure I'm breaking several rules, so go ahead and hurt my feeling, i only have one but it has a quick recovery. I appreciate all advice.
